i have 33" wildpeak mt's they feel great at 32psi cold and run about 35-37 warm. i blelieve Ko's do best and wear good at 35 psi warm and 30 cold. thats how i ran my silverado for 60k miles on one set of KOs
Rubicon on 3.5 MetalCloak with 6/paks
4-1/2" Rockrawler springs in back
Adjustable track bars

Alignment every 10,000
Stock steering dampener
Have not had one steering or ride issue in 37,438 miles. I'm guessing a minimum of 1/3 of those miles have been off road of all types. Rock crawling, mud, snow, speed, slow, sand, hardpack. Every time I get back in the freeway to come home it drives like your basic roadworthy family vehicle. Two previous Jeep's and multiple trucks thru the years. Have never had a comparable 4x4
37" Maxxis E rated. I run around 18-20 on road and down to 8-10 offroad.
Before all the hate comes for such low PSI, believe it or not 18 PSI on the road and I still do not contact the entire cross section of tread. I've done the dirty tire (same as chalk) test on my shop floor. Drives and handles great. Obviously all tires and vehicles are different but I usually run around 18-22psi for a mud terrain on a Jeep and get a good contact patch.
Even the stock BFG's at 35-40PSI is WAY too much IMO. Super harsh ride and they will wear the middle of the tire real quick. They do this for MPG purposes IMO. I ran around 25 before I lifted my JLUR with the stock setup. It'll ride much better and you'll have even tire wear as well.
